My invention relates to furnaces and an object of my improvements is toprovide a continuously moving carriage for the articles to be heatedthat is easy to construct, easily operated and that does not get out oforder and to provide a furnace construction that is eflicient in itsoperation and effective in its treatment of the articles. 7

I secure this object in the apparatus illustrated in the accompanyingdrawings, in which Figure 1 is a plan view of the entire apparatus, theroof of the furnace being broken.

away at a (1 to show the carrier plate and at a the carrier plate isalso broken away to show the construction beneath said plate.

Figure 2 is an enlarged detail section on the line II, II, Figure 1.

Figure 3 is an enlarged section on the line III, III, Figure 1.

Figure 4 is a similar section on the-line IV, IV, Figure 1.

a, a, a, a, is a casing annular in form, as shown in Figure 1,constituting the walls of the furnace. b is the heating chamber. 0 isthe fire-place, or space in which the flame is produced and 0?)indicates flues leading from the chamber a to the chamber 2) along thelateral interior walls of the furnace. cl is the floor plate of theheating chamber b preferably made of carborundum, or other material thatshall easily transmit heat while shielding the carrier plate andarticles thereon from the direct action of the flame.

e is a carrier plate. This is made up of sections 6 e which fit togetherto form the annular plate, which sections are bolted together by meansof ears e e formed thereon. e is a flange turned downward and extendingaround the periphery of the plate e, 764 is a series of rack-teethextending downward around the center of the annular carrier plate 6. nis a stationary plate secured at the bottom of the furnace. v

m is an arm extending horizontally'and pivoted at mn tothe plate 'n. mis a spring tending to raise the outer end of the arm m.

is is a vertically extending lever'arm shaped at its upper end to form apawl to engage the rack 6 The lower end of the arm is is pivoted at lamto the arm m. Thus the spring m acts through the arm m tending to forcethe arm or pawl 70 upward and hold it in engagement with the rack 6 7indicates the motor as a whole. 'This rotates a horizontal shaft g whichcarries, to-

wards its outer end, an eccentrich. j is an eccentric rod its strapfitting around the eccentric h and'its outer end pivoted to the arm is.

r indicates a series of roller discs fitting and adapted to roll upon ahollow track T4, located around and below the inner edge of the plate 6.r is a second series of roller discs located further from the center ofthe furnace than the first series and adapted to roll in a similar trackT The tracks r 'are U-shape in cross-section and are supported on thefloor plate 03 in a suitable position to receive the roller discs T Thecarrier plate 6 is made of a thin metal that will endure the hightemperature and rests upon the series of roller discs 1", 7, so that itcan be easily rotated, rolling upon said discs. There are a number ofroller discs r adapted to turn with their axis vertical and providedwith yieldingly actuated means w to press them against the outer surfaceof a flange e and centralize the carrier plate 6. The discs and tracksare, of course, also made of a heat enduring metal.

8 is the inlet chute and s the outletv chute. t is a pneumatic cylinderadapted to operate a pusher head 4). w indicates a series of gearsconnecting the shaft 9 with the valve of the cylinder 6, so that saidvalve shall be operated at suitable times to discharge the articles fromthe carrier plate 6.

The operation of the above described device is as follows: r

The articles to be heated are fed through the chute .9 upon the plate 6.The engine 7" is then set in motion rotating the shaft 9 and oscillatingthe pawl, or arm, is which arm acting upon the rack-teeth 6* moves thecarrier plate along one notch, or more, asthe case may be, at eachoscillation. WVhen the articles comeopposite the discharge chute f thepusher plate 41 is oscillated by the pneumatic cylinder t to push thearticles off the plate and discharge them into the chute f Should theplate 6 warp out of its normal shape the pawl is will adapt itself tothis condition and still engage the rack teeth and actuate the plate.

lVhat I claim is:

1. In an apparatus of the kind described, the combination of astationary heating chamber, a fire-place beneath the said chamber and afiat carrier made of thin heat enduring metal rotatable in said chamber,said chamber having a bottom permeable to heat but adapted to shieldsaid carrier from the direct contact of the flame, said carrier platebeing provided with a circular rack at its lower surface, a verticallymovable pawl engaging said rack, and yieldingly held in engagementtherewith and means for oscillating said pawl for the purpose described,

2. In an apparatus of the kind described, the combination of a rotatablecarrier plate having a toothed rack, a pawl-engaging said rack at oneend, the other end of said pawl being pivoted to a part that is movabletoward and away from said plate but restrained from other movement,means for yieldingly forcing said part tOWi IfCl. said plate, and

means for actuating said pawl about said part, 7

In testimony whereof, I Sign thls specification. 7
